What name do you go by most often?
David. As an online moniker, probably freedomischaos. It's been that for as a long as I care to remember. Sometimes someone else snags it and it makes me annoyed, but so it goes.
What do I do for a living?
Some would say live, but I fear that's a bogus answer and needs a lot more time to explain it.
I sometimes describe it as a mix of Software Engineering and Tech Support. I guess that's probably or technically Application Support, but it also all the related technologies that go into that and I end up with a few hats.
I'm a terrible programmer, but I can generally read and understand most human-readable code (e.g. java/python/javascript). I just don't care to do much of it, though it's slowly become more of a requirement in my life and job.
Have you considered a better hobby?
All the time actually, but it's difficult considering that I think this is my special interest so it tends to devour a lot of my time no matter how much other considerations I give it.
